[webkit-qt] QWebPage leaking network threads?

[İsmail Dönmez]

It gets even more interesting. I enabled REQUEST_DEBUG in loader.cpp and;

1st load;

HOST  COUNT 1 LOADING data:image/gif;base64, [...]
HOST  COUNT 2 LOADING data:image/gif;base64, [...]
HOST  COUNT 3 LOADING data:image/gif;base64, [...]
HOST  COUNT 2 RECEIVED data:image/gif;base64, [...]
HOST  COUNT 1 RECEIVED data:image/gif;base64, [...]
HOST  COUNT 0 RECEIVED data:image/gif;base64, [...]
HOST www.google.com COUNT 1 LOADING
http://www.google.com/csi?v=3&s=mog&action=default_load_1&e=0&mog_d=0&mog_ui=4&rt=nav.210,foot.1002,ol.3482,prt.3482
HOST www.google.com COUNT 0 RECEIVED
http://www.google.com/csi?v=3&s=mog&action=default_load_1&e=0&mog_d=0&mog_ui=4&rt=nav.210,foot.1002,ol.3482,prt.3482

Close QWebView, create it again, 2nd load;

HOST www.google.com COUNT 1 LOADING
http://www.google.com/csi?v=3&s=mog&action=default_load_1&e=0&mog_d=0&mog_ui=4&rt=nav.2,foot.2,ol.15,prt.15
HOST www.google.com COUNT 0 RECEIVED
http://www.google.com/csi?v=3&s=mog&action=default_load_1&e=0&mog_d=0&mog_ui=4&rt=nav.2,foot.2,ol.15,prt.15

Close QWebView, create it again, 3rd load;

NO REQUEST LOG OUTPUT!

So the request does not even come to loader at 3rd load, any ideas which
part of the WebKit to debug next?
